Answer 1

The correct option is D Rattan Palm

Rattan belongs to the palm family (Arecales or Palmea) and is found from sea level up to 3,000 m. Around 600 species and 13 genera of rattan are known. Although most rattan species are native to the tropical regions of Africa, Asia, and Australia, there is a large variety in their distribution. Commercially-used rattan usually grows in hilly tropical areas, with a mean annual temperature of 25° C and an annual rainfall of -2,000 mm. As a result, the main area for rattan production is in the tropical regions of South and Southeast Asia. There are different types of rattan palms, such as high or low climbers, single stemmed or clustered rattan species. Some have very short and underground stems. Several rattan species are known to reach lengths of 100m. Rattan sheaths have spines for protection, along with ‘whips’ that are also covered with spines. These play a major role in supporting the rattan as it grows over trees and other plants in the rainforest.

So the correct option is 'Rattan Palm'.
